Hi. I am doing some pre-planning and was wondering which tide tables to be referring to for the beach crossing at owen point. I will be at thrasher cove (hopefully body willing)on aug 22, 2011 and would like to hike to owen point. Here is the report for port renfrew on that day. What time would i have to start in order to make the passing before tides reaches above 1.8m which is 2.5km from thrasher cove. Any help with this is greatly appreciated. First of many questions.

| Karen, use the rule of 12. For example, if your tide change is an even 6 hours between changes like 0600 with the next change be 1200 you have a 6 hour = 360 minute span unit. Now figure out how much that change in height will be. For example if the low is at 0600 and is 1 meter and the high at 1200 is 3 meters you have a 2 meter adjustment. Good so far? Now divide 2 meters by 12. So each portion you will use is 1/12. Here is the essential piece. In the first part of your 6 hour span, the tide will change 1/12 of the total. In the second hour it will change an additional 2/12ths. In the third hour 3/12ths more. In the fourth hour 3/12ths more again. In the fifth hour 2/12ths. And in the final hour 1/12 change. This pattern is because the tide speed increases so it fills up or down most in the 3rd and 4th parts of the six parts and then the flow decreases again as it nears the change. Not all tide changes are a full 6 hours so you should convert it to minutes and divide by 6 for your six parts and then the total tide elevation change by 12ths. This is a darn good way to judge where a tide will be on a beach for passing along it and/or setting up a tent. Hope this helps. |

Your post"Hi. I am doing some pre-planning and was wondering which tide tables to be referring to for the beach crossing at owen point.

In response to your question. The maps indicate that Owen Point is passible at tides below 1.8 m.
From your tide chart provided. It indicates the tides will be lowest at 3:07 am at 1.1 M and at 13:13 hrs at 1.8 M. (Anyways, the Parks people will stick on a tide chart on your map. I think they usually tell hikers to add 1 hr on the times though.)
Travelling along that coast at 3am in the dark would be insane. It is a long boulder field and the boulders are big and slippery. One mistake and a "face plant" will end your trip pretty fast. A bit of advice as you hike along the boulder field just remember it is better to step into the tidal pools and get your feet wet rather than to fight a slip/fall and end up "face planting".
According to your tide chart it shows that the high tide will be at 09:55 am with a high of 1.9 M. Basically it is 0.1 metres higher than passible. But the next low tide is at 1.8m at 13:13 hrs. So that would mean the tide is not going to drop that much between 09:55 and 13:13 hrs.
You will have to make a decision on what you want to do. Better know how fast you can safely travel across a slippery coastal boulder field.
Here's my opinion of choices:
1. Go early in the morning ie. 4:30 am and try to make it to Owen Point before high tide at 09:55 am. Wake up at the crack of dawn.... it would feel like an adventure.
2. Go later in the morning ie. 8:00 am and you know your feet are going to maybe get wet if you hit Owen point at around 09:55 am. Nothing like getting the feet wet.
3. Go way later in the day and try to hit Owen point by 13:13 hrs. But remember that the tide will look pretty much the same all day. But be aware that the next high tide at 20:09hrs will be at 2.7m.
4. Go the inland route. Climb back up to the trail and hoof it through the rain forest.
Things that may help you in your decision will be precipitation. If the boulders are too slippery and wet then they become hazardous to traverse. Be flexible in your plans. If the ocean sounds angry ie if it was rainy or looks stormy then there will be a tidal surge and the waves will be higher than the tide chart indicates.
If it were me and I really wanted to challenge myself and do the boulder field and see Owen Point. If the weather was calm and sunny. Then I would wake up early and take option 1. ( of course adjust your time accordingly. If you are a slow hiker then wake up earlier.) Give yourself extra time to travel at a safe speed. Consider the speed of the slowest hiker in the group. Do not rush because a person can get easily hurt from slipping on those boulders. I have taken this boulder route before. I did it but I have never taken it since. Just be careful. Keep your pack tight so it does not throw your balance off. A good sturdy stick may help. Have fun on jumping the small surge channel. ...what a rush. Makes me want to take that route again.
Good Luck. |
